MUD-LUG FOB, AUTOMOBILE-WHEELS.

Specification of Letters Patent.

T 0 ZZ whom t may conce/mt.'

it known that l', Josnrrr A. Rsrrsnr, a citizen oit the United States, residing at Beatrice, in the county of Gage and State of Nebraska, have invented a new and useful Mud-Lug for iutomobile-lheels, of which the following is a specification.

This invention relates to new and useful improvements in anti-skid attachments for automobile tires and wheels, and it is the primary object oi the invention to provide a device oi" this character which may be readily and easily applied to any wheel conruction now in use.

further object ot the invention is to provide anti-skid devices including curved body portions adapted to encircle the tread of the tire associated therewith, together with means l'or locking the body portions to the wheels.

W ith the foregoing and other objects in view which will appear as the description proceedsr` the invention resides in the combination and arrangement of parts and in the details ot construction hereinafter descriled and claimed, it being understood that changes in the precie embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing i'rom the spirit of the invention.

Referring to the drawings Figure l illustrates a fragmental view of a pneumatic tire showing the invention as applied thereto.

Fig. 2 illustrates a sectional view taken on line 2-2'of Fig. l, and

Fi g. 3 illustrates a sectional view taken on line 8-3 of Fig. 2.

Referring to the drawing in detail, the reference character 5 designates the body of the anti-skid device, and the same includes a curved inner portion` curved to conform to the tread of the usual automobile tire, the outer surface thereof being provided with the transversely extending ribs 6, which as shown, are preferably larger at the ends thereof, so that the same will present substantially wide shoulders for Contact with the surface over which the wheel is operating, the transversely extending ribs being connected by the longitudinally extending ribs 7, which ribs prevent lateral moveo the wht-iol on which the same is supn ported, when lateral pressure is directed thereto.

Disposed adjacent oneJ of the side edges of the body 5, is an opening'S, which opening provides the bar 9, for accommodating the eye l() formed in the lower end of the connecting link 11, the other end of which is bifurcated as at 12, and apertured as at 13, to receive the pivot pin 141: passing through the apertures 18, and through suitable apertures Jformed in the ears 16, forming a part of the locking lever 17, the ears being disposed adjacent one end of the locking lever 17.

This locking lever 17 comprises a strip of material bent intermediate its width to provide opposed iianges 18, the flanges 18 being apertured adjacent the extreme inner end thereof as at 19, and embrace the lower end o the arm 20, the pin 2l being provided Jfor pivotally connecting the locking lever 17 to the arm 20, so that movement of the locking lever l? produces a relative movement of' the arm 20, the upper end of which exends at right angles to the body portion thereof, to provide a pin 20', the same being constructed to be positioned within the the opening 22, forming a part of the yoke 23, for connecting' the yoke with one side of the body portion 5.

The yoke 23 comprises angularly extending arms 24 the arms extending at an angle to conform to the curvature of the inner edge of a telly, the same being provided with a central socket 25'which accommodates the threaded shank of the set screw 2G, the lower end of which has connection with a movable clamping element 27, which also includes angularly disposed sections 28, and and an upwardly extending flange 29 engaging one of the side walls of the yoke 23 to prevent rota-tion of the clamping element 27, when the set screw 26 is being manipulated to force the clamping member 27 into engagement with the telly of a wheel, there being however, a strip of leather 30, riveted or otherwise secured to the inner surface of the clamping element to present a smooth surface `for contact with the telly of the wheel to eliminate any possibility of the device marring or scratching the same.

An arm 3l is formed integral with the yoke 23, and one end thereof extends into close proximity with the opposite edge of which has a section 34 pivotally embracing the pin so that the arm 31 will be permitted to have a free pivotal movement with' relation to the body 5 to facilitate the applil cation of the device. Y

The locking lever 17, is provided with a notched portion 36, formed in one of the flanges 18, which notched portion embraces the pin 20 when the arm 20 is in its locked position, the lever 17 contacting with the spring clip 37 in its movement to its locked position, which spring clip 37 engages one of the flanges 18 for securing the saine against displacement under ordinary conditions. Y

VIn the operation, anti-skid devices constructed in accordance with the present invention are disposed throughout the periphery of the tire to which the same are to be applied, the number of anti-skid devices employed, being determined by the conditions of the road over which the device is moving'.

1n the'application vof a device of this character, it is only necessary to remove the pin 20 from the opening 22, by moving the locking lever to a position out of contact with the arm 20, whereupon the yoke is positioned over the inner surfaces of the 1 telly of the wheel, and the pin 20 Vis located in the opening 20. The lever is now moved into engagement with the arm 20, so that the device is locked to the wheel.

Having thus described the invention, what is claimed as new is 1. An anti-skid device for automobile tires including a body portion, a' yoke having an opening formed therein, a connecting'link having pivotal connection with the yoke, an arm having a Vpin formed on one arm thereof, said pin adapted Vto engage within the opening, a locking lever having pivotal connection with the link and arm for locking the arm to prevent displacement of thepin within the opening, and a clamping member operating in conjunction with the yoke.

2. In an anti-skid device for automobile tires, a body portion, pivoted link members connected to the body portion, anV arm having connection with one ofthe link members, a yoke formed integral with the arm, said yoke having a threaded opening, a clamping member Vassociated with the yoke, threaded means passing through the threaded opening of the yoke and having connection with the clamping member for moving the yoke and clamping member with relation to each other, and a locking lever having connection with the opposite link member andthe yoke for securing the yoke and body portion together.

3. In an anti-skid device i'or automobile tires, a body portion, an arm having a yoke formed integral therewith, means for pivotally connecting the arm to the body portion, said yoke having a right angled keeper, a locking arm having a right angled end positioned in the opening, and a locking lever adapted to move downwardiy embrace the arm for securing the saine in position.

4. InV an anti-skid device for automobile tires, a body portion, an arm having a yoke formed integral therewith, means for pivotally connecting the yoke and the body portion, said yoke having a keeper, an arm having a right angled end adapted to be positioned in the keeper, means Vfor pivotally connecting the arm and body portion, a locking lever eccentrically connected with said means, said locking lever having depending lateral flanges, one of said ianges having a out out portion adapted to embrace the right angled end to secure the same against movement within the keeper, and a spring clip for vsecuring the locking lever against movement.

ln testimony that I claim the foregoing as my own, I have hereto aiiixed my signature in the presence of two Witnesses.
